The folly of using an onboard GPS system appears to have led PJ police to a suspected Islamic terrorist, en-route from Portugal to France.

As reports today explain, the man - described only as someone from the Maghreb (northeastern region of Africa) - stole a LandRover jeep from Lisbon, and would quite possibly have “gotten away with it” had he not activated the vehicle’s GPS system.

In doing so, the GPS coordinates pinged through to the car’s owner, and he in turn was able to advise police on its route.

A road block on the A1 motorway near Abrantes caught the "magrebino" red-handed.

But what appeared to be a simple case of carjacking then turned sinister.
